Test Current: 1mAAccuracy is stated as ±℃ and is based on a Platinum RT100 (DIN IEC 751, 385 type) RTD with less than 10Ω lead resistance. The accuracy listed in the table below are valid only when using the 4-wire RTD measurement function. Specifications do not include probe accuracy, which must be added.

*15 Typical measurement rates with auto-zero off, delay = 0, display off, auto range off and math off.*16 Maximum measurement rates for 0.01% of AC step. When DC input varies, additional settling delay is required.*17 For remote operation or external trigger using default settling delay.*18 Speeds available in OutG SW 1.0.700.18 or higher. Note that the measurement rates for RS232 can vary depending on the baud rate chosen. If the baud rate selected is 115,200, the maximum measurement rate is 711 measurements. The LAN bus has a maximum measurement rate of 963 measurements.
